Abstract

The article explains the influence of number of passes on the parameters of the microstructure of D16 aluminium alloy during rolling in the corrugated rolls, and the impact of the drafts while rolling of the strips on the longitudinal wedge mill.A comparative evaluation of the grain size of the ultrafine grained structure was conducted after rolling strips in the corrugated rolls by various passes, and after rolling on the longitudinal wedge mill at deformation temperature of 320 °C.It is shown that the sheet material of D16 aluminium alloy ensures uniform formation of an ultrafine grain structure with the size of about 220 -240 nm, which leads to increased strength properties of the alloy and preserve good ductility.
